Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
In high-resolution camera modules, where every 0.01 mm counts, the choice of interconnect is critical. The AWG42 micro coaxial cableis a proven solution for transmitting high-frequency video and control signals in ultra-compact spaces. However, its ultra-fine structure makes the jacket materialthe decisive factor for long-term reliability. This article explores the key properties of AWG42 cables and how selecting the right jacket can significantly extend the service life of your camera module.
AWG42 (≈0.08 mm diameter) is at the extreme end of micro-coaxial cables, designed for applications where space is paramount. It’s commonly used in:
These applications often use 0.4 mm pitch micro-coax connectors(e.g., KEL USL20 series) that are explicitly recommended for #42 AWG cables, highlighting its prevalence in compact imaging systems.
The small cross-section of AWG42 presents inherent electrical challenges that impact long-term performance:
For AWG42, the jacket is not just a protective layer; it’s integral to the cable’s performance and lifespan. Key requirements include:
Different jacket materials offer distinct trade-offs for AWG42 cables. Here’s a comparison of the most common options:
| Material | Key Properties | Pros | Cons | Best Use Cases |
|---|---|---|---|---|
| FEP(Fluorinated Ethylene Propylene) | – Temp:-65°C to +200°C – Dielectric:Low loss – Clarity:Good | – Excellent chemical resistance – Good flexibility – Cost-effective | – Slightly higher loss tangent than PTFE/PFA – Softer than PFA | General industrial cameras, cost-sensitive medical devices. |
| PFA(Perfluoroalkoxy) | – Temp:-65°C to +260°C – Dielectric:Very low loss – Durability:High | – Superior chemical & thermal resistance – Excellent mechanical toughness – Ideal for repeated bending | – Most expensive option | Medical devices (autoclave), aerospace, automotive under-hood. |
| PVC(Polyvinyl Chloride) | – Temp:~105°C – Cost:Very low | – Inexpensive – Flame retardant (UL94V-0) – Good general-purpose protection | – Poor high-temp performance – Higher dielectric loss – Environmental concerns (RoHS) | Non-critical, low-cost consumer electronics. |
| PUR(Polyurethane) | – Temp:-40°C to +80°C – Flexibility:Excellent | – Very high flexibility & abrasion resistance – Oil & tear resistant | – Limited high-temperature range – Can absorb moisture | Robotics, moving cable chains, industrial environments. |
| LSZH(Low Smoke Zero Halogen) | – Temp:Varies (typically ~105°C) – Emission:Low smoke, no halogen | – Safe for confined spaces – Meets strict fire safety codes | – Mechanical properties vary by formulation | Public spaces, transportation, ships, medical facilities. |
